how would I check for string
<something> in var string = "some chars <something> somechars"


You can use String.match():
var res = string.match(/<something>/g); // ["<something>"]
If there is no match, the value of res will be null. See example on JSFiddle.

So I’m trying to check names through an array and I don’t want to have to use
if (<array name>[0,1,2,3,4,5,6,7])
{ code in here }

depend on what you are trying to do u can use forEach or map
let arr = [1,2,3,4,5,6,7,8,9,10];
arr.forEach((item)=>{
console.log(`${item} is greater than 5 : ${item>5}`)
})

I need to check if the value of the input consists of numbers(0-9). Thanks for helping.

You can use Regular Expressions:
var result = /^[\d]+$/.test(yourInput);

Try to use isNumeric like this:
if($.isNumeric( input ) && parseInt(input)<10 && parseInt(input)>=0){
...
}

I have a string
var str="[a54hy 8:45pm],[f57gh 9:20]"
i need to get
[f57gh 9:20pm]
I don't want to use split since the string length can be anything

This worked for me. where id is f57gh
var re='\\['+id + '([a-z0-9: ]+)\\]';
var rematch=RegExp(re,'g');
var mydata=str.match(rematch);
alert(mydata); //[f57gh 9:11am]

so i have this array:["bilder/test/_PRF6367.JPG.jpg", "bilder/test/_PRF6372.JPG.jpg", "bilder/test/_PRF6374.JPG.jpg"]
how do i split the individial strings JUST into _PRF6367.JPG.jpg etc.

Use Array.prototype.map to create new array of modified strings:
["bilder/test/_PRF6367.JPG.jpg", "bilder/test/_PRF6372.JPG.jpg", "bilder/test/_PRF6374.JPG.jpg"].map(function(str) {
return str.split('/').pop();
});
Result:
["_PRF6367.JPG.jpg", "_PRF6372.JPG.jpg", "_PRF6374.JPG.jpg"]

Can you help me please to get some param from an URL.
Url should be the form : http.www.lolilol.com/gallery/Param1/Param2/Param3/
I need to get Param1, Param2 and Param3.

A simple solution :
var params = document.location.pathname.split('/').slice(2);
This gives you the array ["Param1", "Param2", "Param3"]

The regex would be http://www\.lolilol\.com/gallery/(.*)/(.*)/(.*)/ assuming you meant http://www.lolilol.com/gallery/Param1/Param2/Param3/
